Seas given as significant wave height, which is the average

Synopsis for the Gulf of Mexico

.SYNOPSIS...A 1016 mb low pres centered near 28N92.5W will move
ESE across the Gulf of Mexico today, with a cold front extending
SSW and a warm front extending E from the low. The gradient
between the low and strong high pressure over the SE United
States will cause winds to gale force in the SE Louisiana to the
Alabama coastal waters late this morning, and in the NE Gulf
offshore waters this afternoon. Gale-force winds are also
forecast offshore Veracruz this afternoon and evening. The low
will shift toward South Florida by late tonight while the cold
front slowly moves eastward, stalling and weakening by mid-week.
Fresh to strong N winds are expected elsewhere behind the front
through this evening. Scattered showers and thunderstorms are
expected with the low and front. Looking ahead, a stronger cold
front is expected to move off the Texas coast Thu evening
followed by near-gale to gale force winds and rough to very
rough seas across the basin through Fri night, with strong gales
possible off Veracruz.
